Low-angle, range-flank faults in the Panamint, Inyo, and Slate ranges, California: Implications for recent tectonics of the Death Valley region

摘要

Four of the mountain ranges near Death Valley, California, display exhumed, low-angle normal faults on their flanks, features originally referred to as turtleback structures. These fault surfaces are smooth, planar to curviplanar, and defined by faceted spurs and coincident interfluve crests. The lowest parts of these faults are overlain in tectonic contact by poorly indurated fanglomerate, and locally by Quaternary volcanic rocks. Steep fault scarps in alluvium are present at the foot of each turtleback-type flank.
